## GCF of 32 and 48 by Long Division Method.

1. Divide the larger number (48) by the smaller number (32):
• 48 ÷ 32 gives a quotient of 1 and a remainder of 16.
2. Replace the larger number with the smaller number (32) and the smaller number with the remainder (16):
• Now, divide 32 by 16.
• 32 ÷ 16 gives a quotient of 2 and a remainder of 0.
3. When the remainder is 0, the divisor at this step is the GCF:
• The last divisor, which is 16, is the GCF.

Therefore, the GCF of 32 and 48 is 16.
